Generic Name: prothrombin complex concentrate (human) (pro-THROM-bin)
Brand Name: Kcentra
Patients are treated with vitamin K antagonists (eg, warfarin) because they have health problems that put them at increased risk for blood clots. Very bad and sometimes deadly blood clots have occurred after using Kcentra to reverse the effects of vitamin K antagonists. Talk with your doctor about using Kcentra to reverse the effects of the vitamin K antagonist, especially if you have ever had a blood clot. Tell your doctor if you have had a blood clot, heart attack, a certain blood problem (disseminated intravascular coagulation [DIC]), stroke or transient ischemic attack (TIA), chest pain, or severe blood vessel disease within the past 3 months. You need to be sure that the benefits of using Kcentra outweigh the risks.
Kcentra is used for:
Treating bleeding problems caused by a vitamin K antagonist (eg, warfarin). It may also be used for other conditions as determined by your doctor.
Kcentra is a human clotting factor complex derived from human plasma. It works by increasing the amount of certain clotting factors in the blood, which helps the blood form clots and stop bleeding.
Do NOT use Kcentra if:
- you are allergic to any ingredient in Kcentra, heparin, or to other products that are made from human plasma
- you have DIC
- you have a history of low platelet counts after taking heparin
Contact your doctor or health care provider right away if any of these apply to you.
